ALARM OPERATION:
The terms ‘failsafe’ and ‘non-failsafe’ are defined above as
implemented in the PQM. If an alarm is required when the PQM is not operational due
to a loss of control power, select failsafe operation. Otherwise, choose non-failsafe.

NON-FAILSAFE:
The relay coil is not energized in its non-active state. Loss of control power will cause the
relay to remain in the non-active state. That is, a non-failsafe alarm relay will not cause an
alarm on loss of control power. Contact configuration in the Wiring Diagrams is shown with
relays programmed non-failsafe and control power not applied.
FAILSAFE:
The relay coil is energized in its non-active state. Loss of control power will cause the relay
to go into its active state. That is, a failsafe alarm relay will cause an alarm on loss of
control power. Contact configuration is opposite to that shown in the Wiring Diagrams for
relays programmed as failsafe when control power is applied.
